Given numbers are 438,657,155,719

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 438,657,155,719 is 146438730.

Find LCM of 438,657,155,719 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

3 x 73 x 2 x 3 x 155 x 719 = 146438730

Therefore, the lowest common multiple of 438,657,155,719 is 146438730.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

438 x 657 x 155 x 719 = 32070081870

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

438 : 1, 2, 3, 6, 73, 146, 219, 438

657 : 1, 3, 9, 73, 219, 657

155 : 1, 5, 31, 155

719 : 1, 719

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,657,155,719, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

657:3x 3x 73

155:5x 31

719:719

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 73 = 219

Therefore, the value for common factors is 219.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 32070081870/(1x219)

LCM = 32070081870/219

LCM = 146438730

Thus, we can understand that the LCM of 438,657,155,719 is 146438730.
